A fascinating new study from researchers in Japan indicates our metabolism of dietary proteins is influenced by when we consume meals. The study found protein consumed early in the day promotes better skeletal muscle health and growth.

When plants perform movements such as curling their leaves, they do so by drawing water into the cellulose fibers in that part of their "body." Scientists have now replicated that technique to produce self-folding paper structures.

Researchers have grown “forests” of carbon nanotubes (CNTs) longer than ever before. Using a new method, the team grew bunches of nanotubes up to 14 cm (5.5 in) long, which should help make it easier to scale up production of this versatile material.

While it's possible to 3D-print plastic or metal items, printing single items made of both is quite difficult. Scientists have developed a method of doing so, however, that may lead to increased production of 3D-printed electronics.

3D printed objects do tend to have a low-res look to them. This is because there are grooves visible between the deposited layers of material. While there are methods of smoothing down the ridges on either side of those grooves, scientists have developed a technique that they say is superior.

Tattoos could soon have more practical uses. A team of researchers from Waseda University in Japan has developed a simple new method to manufacture electronic tattoos, printing the conductive “wiring” with a basic inkjet printer and joining components without the need for solder.

Hydrogen has great potential as a future clean energy source, but it's difficult to store safely. Now a Japanese research team has invented a compact, flexible polymer that could lead to a plastic container of hydrogen that's safe to carry in your pocket.

A robotic avatar that connects people in new ways will go on sale later this year.

Jukusui-Kun is a polar bear-shaped robotic pillow equipped with a pulse-oxygen meter and a moving paw that gently touches the sleeper's face to stop snoring.
